4 Claims.

My invention relates to improvements in refrigerating device. One of theobjects of "my invention is to provide a cooling cabinet having novelfeatures of construction and employing a minimum number of parts.Another object of my invention is to provide an insulated cabinet havingnovel means of assembling and holding the parts in assembled position.Another object of my invention is 10 to provide a refrigerator wallhaving insulation of varied effectiveness whereby the cold produced inthe lower region of the refrigerating chamber is better insulated thanthe zone near the top.

of said chamber. Another object of my invention is to provide a novelform of refrigerated dispensing means having provision for stirring thecontents.

Other objects and advantages of my invention will appear from thefollowing description, taken in connection with the drawings forming apart hereof, in which:

Fig. 1 is a perspective view showing my invention in assembled form;

Fig. 2 is a similar view showing the cover members in lifted positionand the agitator removed;

Fig. 3 is a perspective view of the agitator unit;

Fig. 4 is a cross-section elevational view of my invention;

Fig. 5 is a cross-section detail of the refrigerant discharge faucet,not visible in Fig. 4.

The main body of the refrigerating device comprising my invention iscomposed of an outer shell it, having an in-turned flange II at its topand an inand up-turned flange l2 at its bottom; and an inner shell [3,having anout-turned flange M at its top, side walls l5, and bottom IS. Acork gasket ll is fitted between the flanges II and I4 and serves toseal the-interior space l8 which is filled with a suitable insulatingmaterial, 29.

The outer shell H1 is formed with an outward taper toward the bottom.The inner shell I3 is preferably cylindrical with substantially verticalwalls. The effect of combining the inner and outer shells is therefore,to provide the space I8, narrower at its top than at its bottom. In thisway it is possible to place more insulating material 26 near the bottomof the shell than near 50 the top. It is desirable to have theinsulating effect increase towards the lower portion of the containerbecause the potential rate of heat transfer between the device,including its contents, and the atmosphere and exterior objects isgreater toward the bottom of the device. Thus,

by providing additional insulation near the bot.- tom, it is moredifficult for the cold to get out.

One of the novel features of my inventionis the simple manner in whichthe above described parts are secured togetheryand which I effect. 5 bymeans of the bottom 2|", having flange portion 22 and suitableindentations 23 to receive the ends 24 of spacing members 25. The latterhave feet 26 which rest in flange l2, and threaded portions 21. By meansof a wrenchthese spacing means can be adjusted to put whatever pressureis desired on the bottom 2! and below bottom I5 of the inner shell. Thepositioning of inner shell l5 within outer shell' l0 and the securing ofa tight joint aroundcork gasket I1 is accomplished by the pressureexerted on bottom 2! by spacing means 25, which is transmitted throughinsulation 28 on the bottom l6 of inner shell I3. This has the advantageof leaving'the exterior of the outer shell [0 without any exposedfastening means, perforations, etc., and is a distinct advantage whenassembling the devices. The open top of the insulated container thus fardescribed is closed bymeans of a cap 30."

The latter is formed of a stamping 3|, having a perforation 32 in itscenterand a down-turned flange 33 at its outerperiphery; and a secondstamping 34 having a perforation 35in itscenter and an up-turned flange36 adaptedto fit against I the cork gasket IT as shown. These'two partsare,.30 held in assembled relationship by'means ofya tubular member 31having flange 38 fitting against member 34 and a swedged ring portion 40bearing against top member 3| at perforation 32. at 4| to allow freepassage of handle 42. Tubular member 31 is also of a suflicient diameterto receive the neck portion 43 of thebeverage container.

Suitable insulation 44 is placed between topuiO members 3| and 34 priorto their beingisecured together by the swedge 40. Y

Any suitable form of beverage container may be placed within theinsulated case described. In the form shown in the attached drawings,the 45 device is particularly adapted to dispensing liquids v whichrequire occasional stirring or agitation to" keep the heavier particlesdistributed evenly throughout the mixture.

The beverage container may be round or any 50 other shape adapted forthe purpose and should be of a dimension smaller than the inner mem-'ber l5, sufiicient to permit the ready insertion of a refrigerant 5|,such as ice, between the two walls. likewise, it should be mounted abovethe The top of tubular member 31 is perforated 35 28. Spacing means 54near the upper portion of container may be employed.

The bottom 55 of container 50 is formed with a tubular outlet 56 whichmay be suitably threaded and projected into nut 51 for one-half of thelatters thickness. A short threaded nipple 58 is threaded into the otherhalf of nut 51,

.the former passing through perforation 5D in Wall [5 and into nut 6|for half its depth. Nut 62 and suitable washers 63 provide a leak-tightjoint around perforation 6!]. The dispensing faucet 64 is insertedthrough perforation 65 in outer case ID and its inner threaded neck 66-is secured in the left half of nut 6|. By filing off a portion of theend of neck 56, it is a simple matter to adjust faucet 64 so that itscrews up tight in nut Si-in an upright position.

A rubber gasket 6'! surrounds neck 66 and prevents the leakage-or lossof insulation material -23. Ther'eason for employing nipple 58 is thatthis construction simplifies the assembly and where it "is desired toinsert a new container 50, 'it is not then necessary to remove thefaucet and nuts BI and B2. The container can be detached from nut 51.

The container 50 is closed at its top by a top member "Hlhaving a flangeH to fit the container flange 12; A neck portion 43 is secured to top 10and through the neck portion passes the handle 42, with attached rod 45,for actuating the agitating member 46. The latter is provided withsuitable perforations M which aid in dispersingthe mixture as the handle42 is moved'up and down prior todispensing a drink.

The inner shell I3 is provided near its base (see Fig. 5) with a tubularoutlet portion 13 on which is threaded for one-half of its thickness anut 14.

A suitable stop-cock 15, having threaded portion 16 is secured in theother half Qof nut 14 through a perforation 11 in outer shell l0. member18, the liquefied contents of the refrig- By removing the screw needle'valve signed and formed as to make their assembly 'a'minim'um task. Thecontainer Y50 and inner shell l3 are assembled, then the cork gasket I1is set on flange 'of inner shell l3 and outer shell 10 is telescopedinto position. The parts are inverted and insulation 20 and 28 inserted,then bottom plate 2! is secured in place and as members 21aretightenedthe insulationis com pressed and inner shell I3 becomesrigidly supported.

I wish it understood that the foregoing desoription is intended to setforth one embodiment of my invention and that I do not intend thereby tobe limited from the structures which are the equivalent thereof andwhich come within the terms of the following claims.
